Abstract

TUBO DE AçO SEM COSTURA PARA POçOS DE PETRóLEO EXCELENTE EM RESISTêNCIA à FRATURA POR ESTRESSE POR SULFETO E MéTODO DE PRODUçãO DO MESMO. A presente invenção refere-se a um tubo de aço sem costura de alta resistência para poços de petróleo excelente em resistência à fratura por estresse por sulfeto que compreende, na base de 0<sym> em assa, C:0,1 a 0,20<sym>, Si:0,05 a 1,0<sym>, Mn:0,05 a 1,0<sym>, Cr:0,05 a 1,5<sym>, Mo:0,05 a 1,0<sym>, Al: 0,10<sym> ou menos, Ti: 0,002 a 0,05<sym> e B:0.0003 a 0,005<sym>, com um valor da equação "C + (Mn/6) + (Cr/5) + (Mo/3)" de 0,43 ou mais, com o saldo sendo Fe e impurezas, e as impurezas P: 0,025<sym> ou menos, S: 0,010<sym> ou menos e N: 0,007<sym> ou menos. O tubo de aço sem costura pode conter uma quantidade específica de um ou mais elementos entre V e Nb, e/ou uma quantidade específica de um ou mais elementos de Ca, Mg e REM. O tubo de aço sem costura pode ser produzido a um custo adaptando-se um processo de produção e tratamento térmico do tubo na linha tendo uma alta eficiência de produção uma vez que um tratamento de reaquecimento para refino de grãos não é necessário.SEWLESS STEEL TUBE FOR EXCELLENT OIL WELLS RESISTANCE TO SULFET STRESS FRACTURE AND PRODUCTION METHOD OF THE SAME. The present invention relates to an excellent high strength seamless oil well steel pipe for sulfide stress fracture strength which comprises, on basis of 0 <sym> in wt, C: 0.1 to 0, 20 <sym>, Si: 0.05 to 1.0 <sym>, Mn: 0.05 to 1.0 <sym>, Cr: 0.05 to 1.5 <sym>, Mo: 0.05 to 1.0 <sym>, Al: 0.10 <sym> or less, Ti: 0.002 to 0.05 <sym> and B: 0.0003 to 0.005 <sym>, with a value of the equation "C + (Mn / 6 ) + (Cr / 5) + (Mo / 3) "of 0.43 or more, with the balance being Fe and impurities, and impurities P: 0.025 <sym> or less, S: 0.010 <sym> or less, and N: 0.007 <sym> or less. The seamless steel tube may contain a specific amount of one or more elements between V and Nb, and / or a specific amount of one or more Ca, Mg and REM elements. Seamless steel pipe can be produced at a cost by adapting a pipe production and heat treatment process in the line having a high production efficiency since a grain refining reheat treatment is not required.
